| Abstract:
The Mitchell line of petunia carries two regulatory gene mutations (an2 and an4) that result in the loss of flower colour by shutting down the anthocyanin biosynthetic pathway. We have transformed the Mitchell petunia with the Lc regulatory gene from maize to determine whether Lc can complement these mutations. The resultant transgenic plants produced anthocyanins in all parts of the plant. This response was sensitive to light intensity. The pattern of expression indicates that the Lc gene has not specifically complemented the resident mutations but has up-regulated the anthocyanin pathway by some other route. | |
